CLARIFIER.

Application filed August 1, 1927. Serial No. 209,935.

The object of this invention is to provide ment 18, which may be of perforated metal, a clarifying or filtering device especially useor of wire mesh, and this element 18 carries 55 ful for purifying gasoline, but adapted for on the inner surface thereof a layer of filterclarifying or purifying water and other ing material, felt or the like being suitable liquids,-the device including a plurality of for the purpose. concentrically mounted basket-like elements each carrying on its inwithin element 18 is a basket or the like 20 ner surface a filtering element, the baskets mounting a layer of filtering material 21, and being nested and the filtering elements of felt this element 20 carries on its upper edge an or the like being of gradually increasing deoutwardly extending flange 22 adapted to grees of porosity, from the outer member to engage the upper edge of the element 18.

the inner member, and means being provided An inner basket or the like 24 mounts or for producing centrifugal action in addition carries a layer of filtering material 25, and 65 to ravity flow. includes an upper flange 26 adapted to rest on A further object is to provide a particular or if desired to be secured to flange 22. The assembly of elements including an outer confiltering element is of relatively coarse textainer, and a plurality of elements of perfoture, but will. remove the larger particles of rated material, or of wire mesh, adapted to foreign material. The intermediate layer of carry a filtering medium, these elements, or filtering material is of finer texture, and the some of them, including upper flanges conouter filtering element is of still finer texture,
